.To all whom it may concern.-

Be it known that I, FRANK H. FOWLER, a citizen of the United States,residingin the city and county of San Francisco, State ofCalifornia,have invented an Improvement in Faucets and Valves; and Ihereby declare the following to be a full, clear, and exact descriptionof the same. My invention relates to a dischargenozzle or faucet whichmay be applied to cans or receptacles of any kind containing liquid fromwhich it is desired to withdraw'the contents from time to time. In thepresent case I have shown it as especially applicable to cans containingoil.

It consists of a dischargepipe or nozzle with an interiorspring-actuated controlling-valve, an air-vent connecting with thenozzle, a means for operatin g the valve and controlling the air-ventsimultaneously, and in certain details of construction which will bemore fully explained by reference to the accompanying drawings, inwhich- Figure 1 is an exterior view of the dischargenozzle, showing theapplication to an oil-can. Fig. 2 is a vertical section through thesame. wing its construc- As shown in the accompan A is a nozzle or spoutprojecting from the can or receptacle, so as to serve for the dischargeof the liquidcontained therein, the spout being preferably inclineddownwardly and outwardly from the receptacle when the latter is inposition to discharge the liquid. The inner end of the spout has apartition B, which closes the upper portion of it, leaving the lowerportion open for the discharge of liquid. The upper portion of thepartition has a small opening I), which connects directly with anair-passage 0, extending along the inner surface of the plate D, throughwhich the dismade. This air-passage is made just where it connects withthe opening band tapers graduallyto its upper end,where is made verysmall, as shown at c. This is for the purposeof reventing the ingrossof'liquid when the spout is opened for ts discharge, the pressure of theair coming ying drawings,

- in through the larger opening at the lower end overcoming any tendencyof the liquid to enter the small opening 0 after the discharge has oncecommenced, so as to produce a vacuum within the can. If a small portionof the liquid should commence to flow through this passage when thedischarge first begins, it will pass into the nozzle A and dischargewith the main body of the liquid, but this discharge through theair-passage, if any, will cease as soon as the liquid flows sufiicientlyto begin to produce a vacuum within the can, after iwhich the liquidwill continue to flow through the larger opening and the air replaces itthrough the smaller one.

In order to control the liquid-discharge, I haveshown a valve orclosing-stopper E,Which may be made of cork or any other suitablematerialfnot easily acted upon by the oil or other liquid contained inthe vessel. This valve is secured to the end of an elastic arm F, therear end of the arm being fixed to the plate through which the nozzleopens at such .a distance from the valve as to allow the necessarymovement to open the valve whenpressure is applied to it, the elasticityof the spring again closing it as soon as the pressure is removed. Inorder to actuate this device, I have shown a stem G passing through asleeve H, .havin g its inner end connected with the spring and having amilled head or other means I fixed to its outer end, by which it iseasilyjoperated. \Vhen this stem is pushed inwardly, it forces thespring and valve back, and thus exposes the discharge-opening of thenozzle. When released, the action of the spring is sufficient to'closethe valve and force the stem outward to its normal position. The stempasses through the air-passage (1, pie viously described, and when thestem is in its normal position it also closes the air-passage, bjeeauseit is of suflicient diameter to fill the passage. When the stem ispushed inwardly, so as to open the valve, a portion of the stem, whichis cut away or made smaller, as shown at 11, for that purpose, isbrought into line transversely with the air-passage, thus making theair-passage continuous. The device may thus be operated by pushing thestem inwardly, so as to simultaneously open the liquid-dischargevalveand to make the air-passage continuous for the inlet of air.

In some cases, as for heavy liquids, I may make the nozzle A largeenough at the base to allow the air-vent to pass through the up- ICOgage the inclined surface J upon the sleeve .valve is closedand when itis opened, I have shown a small lug or projection 1 which when the valveis closed may be turned so as to en- H, through which the stem passes,and this will act to draw the valve closely against the inner end of thenozzle or the opening thereto, and thus prevent any discharge or leakageat that point. By turning it in the opposite direction it isbrought inline with a longitudinal slot, or channel 7c, made in the sleeve,

- and the stem may then be pushed'inwardly,

the lug following the channel k. lis a notch madein ,one side of thisslot or channel at such a point that when the stem has been pushedinwardly andthe valve fully opened the stem may be turned so as toengage withthis slot or depression, and thus retain the valve in itsopen position, so that the liquid may bedischarged as long as desiredwithout any need for pressing upon the stem to keep the valve open.

When applied to oil-cans or packages in which the oil or other liquid issold r01: use, the plate D, carrying the nozzle, valve, and valve-stem,may be soldered or otherwise secured in a depression made in the top ofthe can, and,-if desired, the exterior projecting parts may besurrounded by a protecting-casing which may have a screw-cap to cover;it similar tQ thOSe ordinarily employed int e tins in which oil isdelivered, but this is 0 part of my invention, the latter referringparticularly to the nozzle, valve, air-inlet, and control mechanismhereinbefore describe Having thus described my invention, what I claimas new, and desire to secure by Letters,

Patent, is- 1 1. The combination, with a spout or nozzle for dischargingliquids from containing vessels, of a spring-actuated valve situatedinterior to the vessel and adapted to close the inner opening of thespout, a stem connected with the arm of the valve and having alocking-lug, a sleeve on the exterior of the vessel,

through which the stem passes, having a groove or channel and lateralslots or channels into which said lug may be passed,and an air passageconnecting with the upper part of the spout or nozzle and extending intothe vessel.

2. A device for discharging liquids from containing vessels consistingof a spout or nozzle, the lower portion opening directly into thevessel,the inner end of the upper por ion having an air-passage connected withthe yessel by an opening therethrough said passage extending inwardlyand upwardly, and having anopening in its upper end of smaller diameterthan the one connecting with the nozzle, a valve adapted to close theliquiddischarge opening from the interior, a springarm with which saidvalve is connected, and

a stem connected with the spring-arm and slidable through a sleeveexterior to the vessel, with a means by which it may be actuated to openor close the valve. V

3. A device for discharging liquids from containing vessels consistingof a nozzle, the lower portion of which connects directly with theinterior of the vessel and the upper portion closed by a diaphragm atthe inner end,

an air-passage connecting with. the nozzle through an opening in theupper part of the diaphragm and extending upwardly wlthln the containingvessel, converging to a small inlet-opening at theinner end, a valveadapted to close the liquid-discharge fixed to an elastic arm Within thevessel, a stem movable through a sleeve in the side of the vesselconnected with the elastic arm having an exterior head or means by whichit may be forced inwardly to open the valve, said stem passing throughthe air-inlet opening and having a groove or passage made transverselyacross 'it adapted to coincide and make a continuous passage in theair-inlet when the valve is opened and to move from the air-inlet sothat the-stem closes the passage when the valve is closed. v

4. A device for discharging liquids from containing vessels consistingof a spout or nozzle, the lower half of which has an opening into thevessel and the upper part of the inner end closed by a diaphragm, anair-inlet passage extending within the vessel having its lower endconnected with the spout by a hole through the upper part of thediaphragm and its upper end opening .into the vessel, an elastic armfixed within the vessel having a valve at one end adapted to be closedagainst the interior of the nozzle-opening by the elasticity ot' thearm, a stem connected with the arm and slidable through a sleeve havingthe outer end exterior to the vessel whereby it may be pressed so as toopen the valve and allow it to resume its normal position when the valveis closed, a locking-lug upon the stem slidable in a groove or channelin its incasing tube and adapted to engage with slots or inclines madein the tube so that by turning the spindle, it may be locked when thevalve is closed or when it is opened.

In witness whereof I have hereunto set my hand.
